Inventor: PIEPER HENRI
Filed: 1907-11-04
Granted: 1908-02-13
Abstract: 24,316. Pieper, H. Nov. 4. Gas and explosive-vapour engines.-In a fourstroke-cycle internal-combustion engine having one or more pairs of cylinders with cranks at 180 degrees to one another, there are two distributing-valves for each pair of cylinders, each valve controlling the inlet of one cylinder and the exhaust of the other. The arrangement. is shown diagrammatically in Fig. 1. The valve 19 opens the inlet passage 14 to the cylinder 1 and the exhaust passage 17 from the cylinder 2 simultaneously during the period indicated by the shaded sector of the circle 10, and the valve 20 opens the inlet passage'15 to the cylinder 2 and the exhaust passage 18 from the cylinder 1 during the period corresponding to the opposite sectors A<2>, E<1> of the circle 11. Similarly, two valves only can be used for any desired number of cylinders with cranks at 180 degrees. The valves used are hollow and are constructed so that the cool inflowing gases pass through the hollow valvebody, thereby cooling the part of the valve that is heated by the exhaust gases and is not in contact with the water-jacketed valve casing.

Trays, dishes, &c.-In a daylight developing-apparatus, the plate is released from the darkslide face downwards on to . a holder comprising adjustable grippers mounted on a sliding and rotating shaft. The shaft is moved and rotated to bring the plate through adjacent developing and washing dishes, after which the plate is automatically released from the grippers and delivered down a shoot into a fixing-tank. The lower part of the apparatus containing the fixing-tank is divided off to form a dark-box, and is fitted with sleeves &c. The plate is released from the holder 1, Fig. 1, by a spring claw 5, which enters the thumb space in the ledge 47, pushes tue plate back against the spring 46, and brings it over the ledge 47. The plate drops between two grippers 7, 8 mounted on a rotatable hollow shaft 9. The gripper 7 is fixed, and the gripper.8 is pivoted on a block 8<1> and pressed to grip the plate by the spring 11, but is held back by a cam 12 which engages a roller 8<11> on the end of the gripper when in position to receive a plate. The plate is rotated through a developing-tray 15, and then through the adjacent washing-tray 16. The washing-tray 16, Fig. 4, is cut off at one side against which the plate strikes in washing. The development is watched through an eyepiece opening in the front of the upper part A fitted with a non-actinic glass and normally closed by a shutter with two crossing wings actuated from an external knob. Opposite the opening is a non - actinic window 24 fitted with a hinged reflector. After washing, the plate is rotated back until a stationary cam 29 releases the gripper 8, and the plate drops edgeways into the rack 31 in the fixing-vessel 32. The fixing-vessel travels on a carriage 33 and is moved by a rack and pinion to bring ioto position under the shoot 30 any particular groove indicated by the numbered slide 38<1> attached to the carriage, and seen through a non-actinic aperture 38. The other half 39 of the lower part is fitted as a darkbox, and the hinged front-wall is fitted with the folded sleeve 40. The upper box A fits over a raised frame 42 on the lower part A, and splashplates 43 are fitted to the upper part to throw back any liquid from the dishes 15, 16.

Granted: 1910-01-20
Abstract: 1918. Oppermann @. A., [Hitchcock, H. K.]. Jan. 26. Glass furnaces; discharging.-The molten metal is withdrawn from the tank 1 by a siphon 2 and passes through a conduit 3 to a basin 4, from which it is drawn in the form of the sheet s by rollers &c. 6 as usual. Several siphons of different sizes may be allowed to float in the tank 1, the required one being placed in position by tongs introduced through a hole 7. The shape or material of the conduit 3 is arranged so as to promote uniform cooling. For instance, the conduit may be enlarged at the edges, where radiation is greatest, as shown in the cross-section, Fig. 5, or different material may be employed, as shown in Fig. 6. The thickness of the walls of the basin 4 and the size of the neck 4<a> are arranged to modify suitably the rate of cooling and flow of the glass. Screens 17 are also employed to control radiation from the surface of the glass in the basin 4. At the end of each operation, the glass is melted out of the conduit 3 by burners 10, which direct flames into apertures 9. In a modification, the siphon 2 is replaced by a sliding valve which acts in the manner of a siphon. The nature of the product depends upon the viscosity of the glass, its rate of flow through the conduit &c, 3, the head x of the liquid, and the rate of cooling of the molten metal, and, as these conditions depend upon one another in such a manner that any accidental variation in one is automatically compensated by variations in the others, the nature of the products is uniform without the exercise of skill on the part of the operators.
